Why does my tracker show different data than Instagram/Twitter?

If Keyhole's trackers show different data from another app (e.g. the Instagram app on your phone), it may be for one of 3 reasons:

The app counts posts that are outside the Keyhole tracking date range. If the tracker was started after social conversations took place, the metrics shown on Keyhole will be different. Keyhole does not capture posts prior to a tracker being started.

The app's counter includes private posts which are not visible to third party trackers such as Keyhole. Only public posts are available to Keyhole through Instagram and Twitter's API.

Keyhole only captures posts that has the hashtag in the original post, not posts that had the hashtag added after the post was originally published. Trackers also cannot collect data where the hashtag was posted in the comment section. The app counts posts with the hashtag posted in the comments, and if the hashtag was edited in after publication.

Summary: The app's counter shows a higher number than what is actually visible to users and third party trackers.
